Fun game, except for the following two things: it lags quite hard on my 4-core 3.4GHz with 16GB RAM computer, Flash can be faster than this! And, there's this upgrade where you get parachutists from helicopters or so, but these seem to be more a downgrade than an upgrade to me! These parachutists just bop around instead of dying, creating extra things that make it harder to get all stars.
